I first heard the term “a fifth” when referring to a measurement of alcohol way back 1999 on the song “My Name Is” by some guy whose name escapes me. Haven’t heard much from him since either but I remember at the time wondering what it was.
“I just drank a fifth of vodka, dare me to drive?”
I guessed at the time that it was a fifth of a bottle, so not a huge amount but definitely too much to be driving around.
Then I started hearing the reference in other rap songs and people proclaiming to be wasted off a “fifth” which I thought was a bit lightweightish of them and not in line with their Gangsta rap sensibilities. Also, vodka is rank. We drink whiskey…
So what is a fifth of whiskey?
After some research, it turns out that a fifth actually a fifth of a gallon (US) and was the standard bottle size in the US up until 1980. It is equivalent to a 750ml bottle of liquor today.
So when someone says they are going to drink a fifth of whiskey they are going to drink an entire bottle.
How many shots are in a fifth of whiskey?
That really depends on where in the world you are and how you define “a shot”. In the US a shot is generally a one or one-and-a-half-ounce measure in which case there would be 25 or 16 full shots in a fifth respectively (25.3 and 16.9 to be precise with the cross measurement values).
In the UK a standard shot is generally 25ml or in some places 35ml in which case there would be 30 or 21 full shots in a fifth.
So there you go, now you know all about the fifth… it was Eminem… I remember now because he says it in the song.
